Description

Technical Field

[0001] The invention belongs to the technical field of touch screen testing, in particular to a touch screen light transmission detection device. Background Art

[0002] Touch screen devices have become indispensable devices in today's society because of their easy operation and intuitive display and control. Mobile phones, tablets, smart watches, smart TVs, etc. all contain at least one touch screen. Each touch screen needs to be tested before leaving the factory, especially the light transmittance of the touch screen. The light transmittance test is designed to evaluate the light transmittance of the touch screen to ensure that it can accurately transmit color and brightness information in actual use, avoid visual attenuation, and improve user experience.

[0003] A Chinese patent with announcement number CN213933629U discloses a touch screen detection workbench, which is provided with a slot above the placement slot in the base, and a light-transmitting test board that can slide along the slot is arranged in the slot. The light-transmitting test board can cover the touch screen, and then the illumination component can detect whether there are white spots, light leakage and other phenomena on the touch screen by illuminating the light-transmitting test board, thereby improving the efficiency and accuracy of manual inspection.

[0004] However, in the above-mentioned technology, when testing the transmittance of the touch screen, only vertical illumination is used to test the transmittance of the touch screen, while the detection of oblique illumination is ignored. In actual usage scenarios, it is often impossible for the user's line of sight to always remain completely perpendicular to the touch screen to view the content, because people's viewing angles will have a certain inclination due to specific situations and individual habits, and the touch screen has different light transmittance performance at different inclination angles, and there may be problems such as light scattering and reflection, resulting in inaccurate test results.

At this time, when the moving frame 5 carries the placement frame 6 and the touch screen through the LED beam lamp 2, it can cooperate with the spectral transmittance meter 3 to detect the touch screen.

The touch screen to be detected is supported by the two supporting frame blocks 2 40. In addition, the supporting frame block 2 40 installed on the side of the placement frame 6 close to the resistance push block 2 14 is inclined at thirty degrees to the horizontal plane, and the inclined surface of the supporting frame block 2 40 is in the same inclined surface as the inclined surface of the supporting frame block 1 39. The purpose is to prevent the supporting frame block 2 40 from blocking the light emitted obliquely by the LED beam lamp 2, thereby ensuring that the layout of the detection equipment is scientific and reasonable, and ensuring that every corner of the touch screen can be fully scanned by the inclined light emitted by the LED beam lamp 2 without leaving any blind spots, thereby comprehensively and accurately evaluating the light transmittance performance of the touch screen.

[0043] Working principle: first place the entire device inside a darkroom, then connect the spectral transmittance meter 3 to the external display screen through a wire, then place the touch screen to be tested inside the placement frame 6, and then place the placement frame 6 inside the moving frame 5, and control the start and stop of the electric telescopic rod 9 through the switch button. When the moving frame 5 is driven by the electric telescopic rod 9 and the moving slide bar 12 to move inside the slide slot frame 4 toward the side close to the resistance push block 13, the light emitted by the LED beam lamp 2 is vertical. At this time, when the moving frame 5 carries the placement frame 6 and the touch screen through the LED beam lamp 2, the transmittance of the touch screen under vertical light can be detected in conjunction with the spectral transmittance meter 3. When the moving frame 5 When one side contacts the resistance push block 13, the resistance push block 13 can be pushed out from the inside of the slide groove frame 4, and the moving frame 7 can be moved toward the end where the resistance push block 13 is installed, and the moving plate 15 can be driven to move in the same direction. At this time, the moving plate 15 can be pulled to move through the push-pull slot 16, and the rotating rod 18 can be rotated 30 degrees with the end of the LED beam lamp 2 as the center, and the LED beam lamp 2 can be driven to rotate 30 degrees counterclockwise. When the LED beam lamp 2 rotates counterclockwise, the rope winding column 23 can be driven to rotate counterclockwise, thereby winding the pull rope 24, and pulling the Z-shaped block 25 downward, which can be achieved through the T-shaped slide groove 29 and the T-shaped slider 30. The moving block 31 is pushed to move toward the side close to the push block 13, so that the spectral transmittance meter 3 is driven to move in the same direction through the connecting wire barrel 32, so that the spectral transmittance meter 3 is located at the position where the light emitted by the LED beam lamp 2 is refracted by the touch screen, ensuring that the light refracted by the touch screen is irradiated on the surface of the spectral transmittance meter 3. When the spectral transmittance meter 3 moves toward the side close to the auxiliary inclined plate 8, the top of the spectral transmittance meter 3 will contact the bottom of the auxiliary inclined plate 8, and during the continuous movement of the spectral transmittance meter 3, the connecting wire barrel 32 can rotate counterclockwise inside the sliding block 33 under the resistance of the auxiliary inclined plate 8, and finally the top of the spectral transmittance meter 3 is It fits with the bottom of the auxiliary inclined plate 8, so that the spectral transmittance meter 3 is inclined, and the inclination of the spectral transmittance meter 3 is the same as the inclination of the auxiliary inclined plate 8, so that the light refracted by the touch screen is vertically irradiated on the surface of the spectral transmittance meter 3, ensuring that the spectral transmittance meter 3 can capture the most real and unbiased spectral data, and ensure the accuracy of the device in detecting the transmittance of the touch screen. At this time, the electric telescopic rod 9 and the movable slide bar 12 drive the movable frame 5 to move inside the slide groove frame 4 to the side close to the abutting push block 2 14. The light emitted by the LED beam lamp 2 at this time is at a thirty-degree angle to the normal, which can cooperate with the spectral transmittance meter 3 to detect the transmittance of the touch screen under inclined light.
